I'm using Spider Player. Yes, it's a fully fledged audio player (and the best one there is IMHO), but the footprint is hard to beat (7.5 MB disk space, less than 5 MB memory usage, portability). Spider Player has its own Radio Directory:

Discover thousands of radio stations
around the globe with fast and easy
search in Shoutcast and Icecast radio
directories right within Spider
Player.

If your definition of application includes web apps (as opposed to just traditional desktop programs), check out Slacker Radio. It provides bunch of preset stations with DJs, and allows you to create custom stations based on your favorite songs/bands. Like Spider, the basic version is free but there are "premium" features available if you're willing to pay for them. I've never had problems with it being buggy, but it does require JavaScript.

Other web app radio stations are Pandora and last.fm. Slacker is my favorite of the three, but this is definitely a "your mileage may vary" situation.

"We are deeply, deeply sorry to say that due to licensing constraints, we can no longer allow access to Pandora for listeners located outside of the U.S. We will continue to work diligently to realize the vision of a truly global Pandora, but for the time being we are required to restrict its use. We are very sad to have to do this, but there is no other alternative." - from the Pandora site
